GRAIN- DRIER.

SPECIFICATION forming part of.Letters Patent `No. 294,367, dated March 4, 1884.

Application nieu July 2, m83. (No modem scription, reference being also had to the drawings hereto annexed, in which-Q AFigure l is a sectional side elevation. Fig. 2 is an end elevation with the upper part in section on the line x x of Fig. 1.

A is an oblong frame having two oppositely-inclining shafts, B B2, mounted thereon and adapted to be revolved in any suitable manner. Secured to these shafts, inside the frame A', by

open spiders or rings c, are two sheet-metal cylinders, D D2, having heads E E2, through which the grain is fed by sputs F F2 to the interiors ofthe cylinders, the feed-spout F2 of` the lower cylinder being also the discharge! spout of the upper cylinder, so that the grain discharged from the upper cylinder will run'`- into the lower cylinder. The heads E E2 are loose upon the shafts B B2, and are attached tov the frame A', so that they will not turn, and are smaller than the cylinder, so as to leave narrow slits ci between the heads and cylinders for the escape of the hot air, as herein- The ends of the cylinders Opposite to the heads E E2 are covered by hoods G G2, into which hot-air pipes H H2 lead, so that current-s of hot air may be fed into the cylinders.

b are inclined wingsattached to the insides of the cylinders parallel with each other, and also parallel with the shafts B B2, as shown. rlhe wings b are so inclined as to convey the grain upward on one side nearly to the upper side of the cylinder and drop it down again, so that when thel damp or moist vgrain is fed to the cylinder D through the spout F the upward and drop it down'again several times during its passage throughjthe cylinder, the inclination of the cylinder causing it to run down toward the discharge-spout F2. By this means the grain is thoroughly mixed and stirred and every separate kernel subjected to the action of the hot air, while the latter escapes through the crevices a or 'other openings around or through the head E. The grain runs from the spout F2 into the cylinder D2,Where it undergoes the same treatment, and escapes at F3 thoroughly dried and in proper condition for use.

^ Some qualities or conditions of grain will only require to be treated in one cylinder. While others might require three or more; but Ordinarily two will vbe sufficient.

chine by passing cold air in place of hot air through the cylinders to cool the grain.

Having described my invention and set forth its merits, what I claim is- The combination of cylinder D', adapted to b, hot-air pipe H, and stationary head E', with hot-air exitsa between said head and said cylinder, substantially as and for the purpose set forth. l

In testimony whereof l have hereunto set my hand in presence of two subscribing witnesses.

Heated grain may also be treated in. this mal be revolved,.and provided with angular wings.

wings b will catch and yelevate every kernel
